Abstract

A current mode battery charger controller for controlling a DC to DC converter. The current mode battery charger may include a first error amplifier having an output coupled to a common node. The first error amplifier may be configured to compare a firs signal representative of a charging current provided to a rechargeable battery with a maximum charging current and provide a current control signal in response to the comparison. The current mode battery charger controller may further include an internal compensation network coupled to the common node, and a comparator configured to compare an inductor current signal representative of an inductor current through an inductor of the DC to DC converter with a compensation signal. The need for any external compensation for the current mode battery charger controller may be eliminated.
